Fracture of the vertebral end plate in the lumbar spine has been reported as a rare lesion occurring in the adolescent period. It is characterized by variable degrees of sign and symtom related to the degree of block on myelogram and the level of end plate fracture. Trauma or strenuous sport activity seems to play an improtant role in the production of fracture of vertebral body in the adolescent period. We experienced three cases of fracture of lower lumbar vertebral end plate in teenaged patients, two males and one female. Two patients showed upper end plate fracture with severe neurologic deficit on the involved root level and a strong positive on straight leg raising test, and one patient showed lower end plate fracture with slight neurologic deficit. Two patients with upper end plate fracture were treated with partial laminectomy with removal of fracture fragment and one patient with lower end plate fracture was treated with bilateral laminectomy and posterolateral fusion. The method of treatment will depend upon the type of fracture and the degree of neurologic symptoms. We obtained satisfactory results with posterior decompressive laminectomy and removal of fracture fragment with or without fusion.

BACKGROUND: Induction of general anesthesia with tracheal intubation and skin incision are potent stimuli that can induce increased sympathetic activity, heart rate and blood pressure. We compared the hemodynamic response and catecholamine concentration during general anesthesia with intravenous clonidine pretreatment, a centrally acting -2 adrenoceptor agonist, and without pretreatment. METHODS: Forty ASA I or II patients aged from 20 to 60 years undergoing elective surgery were randomly allocated to two groups. In group I, 5 ml of 0.9% normal saline as control administered intravenously 10 minutes before induction of anesthesia, and anesthesia was induced with thiopental sodium, succinylcholine and maintained with N2O (2.5L/min)-O2 (2.5L/min)-enflurane (1.3~1.8 vol%). In group II, 4 g/kg clonidine diluted in 5ml of normal saline administered intravenously 10 minutes before induction of anesthesia, and anesthesia was induced with thiopental sodium, succinylcholine and maintained with N2O-O2-enflurane (0.5~1.0vol%) and 2 g/kg/hr clonidine was continuously infused. We measured blood pressure, heart rate and plasma catecholamine at preinduction, 1 minute after intubation (T1), 1 (T2) and 30 minutes after skin incision (T3) and compared with group I. RESULTS: There was statistical significance in systolic and diastolic pressure at T1 between two groups. There was statistical significance in heart rate, epinephrine and norepinephrine at T1, T2 and T3 between two groups. CONCLUSION: The elevation of blood pressure, heart rate and plasma catecholamine accompanying tracheal intubation and skin incision may be prevented by administration of intravenous clonidine.

5.Prevalence of HBV DNA in Packed Red Blood Cells.

Assays for HBsAg, HBV DNA, anti-HBc and anti-HBs of 285 units of packed red blood cells supplied by Taegu Red Cross Blood Center were performed to evaluate the correlation between the prevalence of HBV DNA and the serologic markers for hepatitis B virus. None of 285 plasma samples was positive for HBsAg, however, HBV DNA were detected by polymerase chain reaction in 2 samples which both presented only with anti-HBc positivity.. Of 204 samples tested for anti-HBs, 96 samples(47.1%) were positive and among 216 samples tested for anti-HBc, 80 samples(37.0%) were positive. Of 193 samples tested for both anti-HBs and anti-HBc, 80(41.1%) were all negative and 48(24.9%) were positive on both tests. Those samples which showed positivity only to anti-HBc were 25(13.0%). Considering the above results, transfusion-transmitted hepatitis B virus infection could be prevented by discarding anti-HBc positive blood, however, that may bring insufficient supply of donor bloods in the country like Korea where the prevalence of anti-HBc is high. Anti-HBc positive blood unequivocally positive for anti-HBs should be considered noninfectious for HBV and should be allowed to be transfused. It would reduce the amount of discarding donor blood as the routine blood donor screening tests presently used at Korea Red Cross Blood Center supplemented by anti-HBs and anti-HBc testing.

Therapeutic plasma exchange is used in almost every condition in which there is a plasma factor thought possibly to the etiology or pathogenesis of a disease or one of its manifestations. In order to evaluate plasma exchange using fresh frozen plasma as replacement solution, eighty four therapeutic plasma exchanges were carried out in eighteen patients. In standardized procedures, 1.5 times the calculated plasma volume was replaced with a Hartman's solution and fresh frozen plasma. Anticoagulation was achieved using a whole venous blood to 2.5% trisodium citrate in the ratio of 10 to 1. Total calcium, phosphorus, glucose, urea nitrogen, creatinine, bilirubin, alkaline phosphatase, amylase, creatine kinase, IgG, C3, total white and red blood cell count, hemoglobin, and differential count were not significantly affected by the procedure. In contrast, serum cholesterol, total protein, albumin, aspartate aminotransferase, alanine aminotransferase, ionized calcium, IgM, C4 and platelet were significantly decreased by the plasma exchange. All these measurements had returned to the first pre-exchange level within 24 hours, while the C4 and platelet count took between 24 and 72 hours, and the IgM level, between 72 hours and 1 week. These data indicated that in an isovolemic plasma exchange there was a transient but rapidly reversible effect on all the components studied, with C4 and platelet count, returning more slowly to pre-exchange level than the others, and IgM levels responding the slowest. In summary, plasma exchanges using fresh frozen plasma as replacement solution were assumed to be not significantly affected the function of various organs.
